I'm not sure, because the patch notes keep changing.. its not even in the official notes anymore. If anyone has a definitive answer I'd appreciate it, if not I'll be able to tell after our next raid by comparing logs I guess..

Those are Tooltip changes from when 5.0 was released. Those changes were in response to us finding that Rake was better then Shred in most situations. These are the tooltip changes finally catching up. Ferals recieved no damage changes this patch.
